In the early days of the Web, businesses didn’t believe their customers were online, nor did they think the Internet would become a viable medium for customer interaction. Companies were hesitant to build websites, let alone advertise online.

Of course, the Internet ramped up faster than anyone imagined. Companies that hesitated were left behind and those that took action became industry leaders, reinventing their business models to become more efficient and profitable marketers. In this new age of mobile computing, how can you ensure your business remains present? Build a mobile site. Research has shown that web retailers can increase consumer engagement 85% with a mobile-specific website (1).

Think about the 4-inch mobile screen as your new storefront. It may be the most important one you ever have: it’s always open; it’s in the hands of nearly everyone, and it’s increasingly how people are finding your business. As important as it is to have a mobile advertising strategy, it’s even more vital to build a mobile website that delivers a seamless and satisfying experience to your users.

Avoid falling into the trap of marketers in the mid 90’s who didn’t think the Internet would evolve into a viable medium for customer interaction.
